1. Scope
This Privacy Policy explains how YayoBench, an Android phone stress test app developed by ea8885 ("YayoBench", "we", "us", or "our"), handles information when you use the app or visit this website.
2. Information used by the app
To perform benchmarking and show device conditions, YayoBench may access technical information made available by Android, such as:
- device manufacturer and model;
- Android version and basic hardware/CPU characteristics;
- CPU core count, architecture, and workload timing;
- memory information used to describe the device or benchmark session;
- battery temperature or other temperature readings when the device exposes them;
- Android thermal status or throttling-related state when available; and
- benchmark scores, durations, timestamps, and other test results.
This information is used to run the benchmark, display live measurements, apply benchmark guardrails, and let you compare test results.
3. Processing on your device
Tests, temperature readings, scores and history are processed and stored on your device. YayoBench has no account system and no YayoBench server. The app does not send your test results or device readings to us.
If you use Android's backup to your Google account, Android may include the app's stored data (history and settings) in that backup. That backup is controlled by you and Google; we cannot access it.
The app package includes Google Firebase libraries (Firebase AI and Firebase App Check) carried over from its project template. No feature in the current version uses them, and the app does not send test data to Firebase.
YayoBench does not collect your name, email address, contacts, location, photos, videos, microphone recordings, SMS messages, call history, financial information or health information.
4. Device identifiers
YayoBench does not require persistent telephony identifiers such as IMEI, IMSI, or SIM serial number to run its benchmark. Persistent device identifiers are not part of the core benchmarking function.
5. History, settings and sharing
If history is turned on (it is on by default), test results are saved in a database on your device so you can compare runs. You can turn history off or clear it in Settings. The app also stores your settings, your Pro status and how many free tests you have used today on your device.
If you tap Share on a result, Android opens its share sheet and you choose where the result text goes. Once you send it, that app or service's privacy practices apply to its copy.
6. Purchases
YayoBench Pro is sold through Google Play as a monthly or yearly subscription or a one-time lifetime purchase. Google Play handles payment, and we never see your card or payment details. The app asks Google Play whether you own Pro and receives purchase records (such as the product, purchase state and a purchase token) to unlock it. That information stays on your device; there is no YayoBench server to send it to.
7. Sharing and sale of data
We do not sell personal information, and we do not share your test results or device readings with third parties. Information only leaves the app when you share a result yourself.
8. Third-party platforms and services
This website is hosted on GitHub Pages. When you visit it, GitHub may process standard web-request information such as IP address, browser information and request logs under GitHub's own terms and privacy practices. This website does not use advertising trackers or analytics scripts.
If you install YayoBench or buy Pro through Google Play, Google processes information connected with Google Play, such as download, account, payment and purchase data, according to Google's policies. YayoBench does not receive your Google account details or payment information.
9. Data retention and deletion
Data stored by the app stays on your device until you clear history in Settings, clear the app's storage, or uninstall the app, subject to normal Android backup behavior. Because there is no YayoBench account or server, there is nothing for us to delete on our side.
To cancel a subscription, use Google Play › Payments & subscriptions. Purchase records held by Google are covered by Google's policies.
10. Security
Keeping data on your device avoids sending it over the internet. No software or storage method is completely secure, so protect your device with a screen lock and keep Android up to date.
11. Children
YayoBench is a technical utility and is not directed to children under 13. We do not knowingly collect personal information from children.
12. Changes to this policy
We may update this Privacy Policy when YayoBench's features or data practices change. The date at the top of this page will be updated when the policy changes.
